Double batches of cookies or brownies

[Brigita]

Question - If I am doubling a batch of cookies, do I fully double each ingredient, even the baking soda?

I agree... if you're doubling a recipe, double every ingredient. If you were halving a recipe, you'd halve the ingredients as best you could (including 1 egg). When baking cookies, as long as they're the same size, you shouldn't have to adjust the time or temp. If you're making a double batch of brownies, I'd use a larger pan to try and keep the thickness the same and check for doneness at 1.5 the regular baking time.

I always double them without making any changes. When I worked with a pastry chef, we would sometimes try out recipes non-professional sources (that is, recipes not measured out by weight), and multiply the recipes by 10x, without changing the recipe at all. It worked fine.

I'd be interested in reading tips for altering cooking time/heat when doubling or halving a cookie recipe.

Not sure what you mean. There should be no change in the bake time of a cookie unless you're doubling the SIZE of the cookie. Whether you have 2 dozen or 4 dozen cookies to bake has no effect on the baking time.

Yes. That is what I do.
